A 60-year-old female with a history of cirrhosis and low serum albumin presents with dyspnea, impaired ventilation, and pleural pain. A diagnosis of pleural effusion is made, and a watery fluid is drained. When giving report, the nurse will refer to this fluid as

Choice A reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Hyperglycemia is a high level of glucose in the blood, which can be caused by diabetes or other conditions. Nonselective beta-adrenergic blockers do not affect blood glucose levels directly, but they may mask the signs of hypoglycemia (low blood glucose) in diabetic patients.

Choice B reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Dizziness is a common side effect of many medications, especially those that lower blood pressure. Nonselective beta-adrenergic blockers can cause dizziness by reducing the heart rate and cardiac output, but this is usually mild and transient.

Choice C reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Peripheral edema is swelling of the ankles, feet, or legs, which can be caused by heart failure, kidney disease, or venous insufficiency. Nonselective beta-adrenergic blockers do not cause peripheral edema, but they may worsen it in patients with heart failure.

Choice D reason: This is a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Wheezing is a high-pitched sound that occurs when breathing is obstructed, usually due to asthma or chronic obstructive pulmonary disease (COPD). Nonselective beta-adrenergic blockers can aggravate or cause wheezing by blocking the beta-2 receptors in the lungs, which normally cause bronchodilation (widening of the airways). Therefore, nonselective beta-adrenergic blockers are contraindicated in patients with asthma or COPD.

Choice A reason: This is not the agent that the nurse should question. Beta blockers are a class of medications that lower the blood pressure and heart rate by blocking the beta receptors in the heart and blood vessels. They can be used to treat hypertension, angina, heart failure, and arrhythmias. They do not cause edema or hyperkalemia.

Choice B reason: This is not the agent that the nurse should question. Alpha 2 agonists are a class of medications that lower the blood pressure by stimulating the alpha 2 receptors in the brain, which reduce the sympathetic nervous system activity. They can be used to treat hypertension, especially in patients with renal impairment. They do not cause edema or hyperkalemia.

Choice C reason: This is not the agent that the nurse should question. Calcium channel blockers are a class of medications that lower the blood pressure and heart rate by blocking the calcium channels in the heart and blood vessels, which cause vasodilation and reduced cardiac contractility. They can be used to treat hypertension, angina, and arrhythmias. They may cause edema, but not hyperkalemia.

Choice D reason: This is the agent that the nurse should question. Aldosterone antagonists are a class of medications that lower the blood pressure and reduce fluid retention by blocking the action of aldosterone, a hormone that regulates the sodium and potassium balance in the body. They can be used to treat hypertension and heart failure, especially in patients with low renin levels. However, they can cause hyperkalemia, which can be dangerous for the patient. The nurse should question the prescriber about the rationale for prescribing this agent and monitor the patient's potassium level closely.
